These allocations in mzap_update() used to be kmem_alloc() but
were changed to vmem_alloc() due to the size of the allocation.
However, since it turns out this function may be called in the
context of the txg_sync thread they must be changed back to use
a kmem_alloc() to ensure the KM_PUSHPAGE flag is honored.

This commit modifies the user to kernel space ioctl ABI. Extra
care should be taken when updating to ensure both the kernel
modules and utilities are updated. This change has reordered
all of the new ioctl()s to the end of the list. This should
help minimize this issue in the future.

Closes#826Closes#664
Export all the symbols for the ZAP API. This allows external modules
to cleanly interface with ZAP type objects. Previously only a subset
of the functionality was exposed. Documention for the ZAP API can be
found in the sys/zap.h header.
This change also removes a duplicate zap_increment_int() prototype.
